Abstract:
With increasing attacks and internal data theft the organizations must strengthen their database security beyond the traditional methods, especially those databases which hold private data. This can be done by developing a security strategy which is a framework of control mechanisms for authentication, authorization, and access control mechanisms to enforce role separation, database auditing, monitoring, network and data encryption, data masking according to the needs and environment in the organization. To develop a high-quality security strategy detailed knowledge and understanding about the database control mechanisms is needed. So the main purpose of this paper is to give a detailed description of security mechanisms which are available till today and build a security strategy according to the needs and environment of the organization. Using the knowledge gained a working prototype which is a security strategy is designed, developed and evaluated for an organization according to the scenario described which contains the challenges or threats and present security mechanisms used in the organization. Finally a security strategy is developed which can help the organization in protecting their information assets and private data from inside and outside attacks.
Introduction:
Databases contain sensitive and important information about an organization. The basic element of any organization is to protect these information resources that support the critical operations of the organization from unauthorized access, modification, or disclosure.
The major threat of the organization is securing its gigabytes of data from the prying eyes of unauthorized outsiders and insiders attempting to exceed their authority. ...

... managed to introduce changes in the database they were spotted as intruder in the subsequent command. The results of the detection latency and performance overhead are mentioned both in normal conditions and heavy load conditions. The author finally concluded that “The detection coverage was 100%, if we consider the sequence of commands inside the transaction in reality” [Fonseca, 2008].
Limitations of the research: The proposed mechanism for Online Detection of Malicious Data Access technique does not apply to users that execute ad-hoc queries which can be considered as the limitation of the paper.
Relationship to your paper: The concurrent detection of malicious data access capabilities in DBMS will provide an extra layer for security mechanism used. This mechanism can provide another layer of security in the security strategy which is the main aim of my paper.
He acknowledges that criminal justice information needs good security because it is information about citizens, often at their most distressed and vulnerable. “Imagine if someone hacked and even edited video of alleged criminals before they were even charged or of child victims describing their attackers.” He notes that with all of the state and local law enforcement officers in the United States, the data requirement will be huge. The only system that can sustain such a requirement with the latest, most flexible technology would be the cloud. The cloud does pose security risks; however, the FBI has issued a policy that addresses both security and privacy issues.
...ed on how to respond to information security breaches. Regardless of an organization size, there is always the risk of information breaches.
Information Technology is performing a risk assessment on security related areas including physical access, network security, credit card controls, franchise security, end-point security, and several other areas. This risk assessment will show us our strengths/weaknesses and provide an overview of what Buffalo Wild Wings needs to work on. Information Technology in conjunction with other department leaders will provide guidance on our business goals and priorities. One security breach could cripple our future, our customers, and our brand. No one wants to see our tremendous growth get shattered by overlooking simple fixes and common vulnerabilities. A team effort and a focused organization can make our organization strive for decades. Let’s not be the next Target.
Security helps the organization meet its business objectives or mission by protecting its physical and financial resources, reputation, legal position, employees, and other tangible and intangible assets through the selection and application of appropriate safeguards. Businesses should establish roles and responsibilities of all personnel and staff members. However, a Chief Information Officer should be appointed to direct an organization’s day to day management of information assets. Supporting roles are performed by the service providers and include systems operations, whose personnel design and operate the computer systems. Each team member must be held accountable in ensuring all of the rules and policies are being followed, as well as, understanding their roles, responsibilities and functions. Organizations information processing systems are vulnerable to many threats that can inflict various types of damage that can result in significant losses (Harris, 2014). Losses can come from actions from trusted employees that defraud the system, outside hackers, or from careless data entry. The major threat to information protection is error and omissions that data entry personnel, users, system operators and programmers make. To better protect business information resources, organizations should conduct a risk analysis to see what
Due in Week Seven: Outline the Access Control Policy. Describe how access control methodologies work to secure information systems
This project must meet the requirements of DoD security policies and standards for delivery of the technology services. The first requirement we are to discuss is Federal Information Security Management Act (FISMA) which is a United States legislation that defines a comprehensive framework to protect government information, operations and assets against natural or man-made threats. FISMA assigned the National Institute of Standards and Technology (NIST), the responsibility of defining standards and security procedures to be followed and must be complied. There are nine processes NIST outlines to be in compliance with FISMA:
In 1980, James Anderson’s paper, Computer Security Threat Monitoring and Surveillance, bore the notion of intrusion detection. Through government funding and serious corporate interest allowed for intrusion detection systems(IDS) to develope into their current state. So what exactly is IDS? An IDS is used to detect malicious network traffic and computer usage through attack signatures. The IDS watches for attacks not only from incoming internet traffic but also for attacks that originate in the system. When a potential attack is detected the IDS logs the information and sends an alert to the console. How the alert is detected and handled at is dependent on the type of IDS in place. Through this paper we will discuss the different types of IDS and how they detect and handle the alerts, the difference between a passive and a reactive system and some general IDS intrusion invasion techniques.

An organization must not just rely on one person to be able to avoid breaches. Instead the organization needs to extend the concern and awareness to all employees to have a defense at all
Inconsistently storing organization data creates a lot of issues, a poor database design can cause security, integrity and normalization related issues. Majority of these issues are due to redundancy and weak data integrity and irregular storage, it is an ongoing challenge for every organization and it is important for organization and DBA to build logical, conceptual and efficient design for database. In today’s complex database systems Normalization, Data Integrity and security plays a key role. Normalization as design approach helps to minimize data redundancy and optimizes data structure by systematically and properly placing data in to appropriate groupings, a successful normalize designed follows “First Normalization Flow”, “Second Normalization Flow” and “Third Normalization flow”. Data integrity helps to increase accuracy and consistency of data over its entire life cycle, it also help keep track of database objects and ensure that each object is created, formatted and maintained properly. It is critical aspect of database design which involves “Database Structure Integrity” and “Semantic data Integrity”. Database Security is another high priority and critical issue for every organization, data breaches continue to dominate business and IT, building a secure system is as much important like Normalization and Data Integrity. Secure system helps to protect data from unauthorized users, data masking and data encryption are preferred technology used by DBA to protect data.
In fact, according to several studies, more than half of all network attacks are committed internally. To determine the best ways to protect against attacks, we should understand the many types of attacks that can be instigated and the damage that these attacks can cause to data. The most common types of attacks include Denial of Service (DoS), password, and root access attacks.... ... middle of paper ... ...
Databases are becoming as common in the workplace as the stapler. Businesses use databases to keep track of payroll, vacations, inventory, and a multitude of other taske of which are to vast to mention here. Basically businesses use databases anytime a large amount of data must be stored in such a manor that it can easily be searched, categorized and recalled in different means that can be easily read and understood by the end user. Databases are used extensively where I work. In fact, since Hyperion Solutions is a database and financial intelligence software developing company we produce one. To keep the material within scope I shall narrow the use of databases down to what we use just in the Orlando office of Hyperion Solutions alone.
Nowadays, the information is the most treasured asset in an organization, due to it along with the experience represents the input necessary to take appropriate decisions and consequently to have success in the business. Almost all the information and knowledge related with the processes business, goods and services offered by a company, is processed, managed and stored through technology and information systems, thus the security of information has become increasingly important and plays a critical role in the enterprise government.
The first thing that we must consider about Information Security is that there is not a final destination at which we can arrive. IT Security is an ongoing set of processes and activities that requires attention and expertise on a daily basis. It is important to understand that systems are not secured by themselves and it is our responsibility to maintain and improve them periodically as required. It is of vital importance to establish the appropriate mechanisms and requirements in order to support the company’s CIA triad. The following report will provide you guidance about auditing and hardening techniques applied though the 7 Domains by utilizing IT Security Best Practices.
In our world, people rely heavily on the power of technology every day. Kids are learning how to operate an iPad before they can even say their first word. School assignments have become virtual, making it possible to do anywhere in the world. We can receive information from across the world in less than a second with the touch of a button. Technology is a big part of our lives, and without it life just becomes a lot harder. Just like our phones have such an importance to us in our daily lives, database management systems are the same for businesses. Without this important software, it would be almost impossible for companies to complete simple daily tasks with such ease.
